Maxim Integrated MAX6070BAUT18+T Precision Voltage Reference

The MAX6070BAUT18+T from Maxim Integrated is a high-precision, low-noise, low-drift voltage reference that offers a fixed output voltage of 1.8V. This component is part of Maxim's series of advanced voltage references that are designed to provide a stable and accurate reference voltage for high-performance analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and other precision circuit applications.

With an initial accuracy of ±0.04% and a low temperature coefficient of 10ppm/°C (max), the MAX6070BAUT18+T ensures reliable performance over a wide temperature range, making it suitable for demanding environments. The low noise specification of 11.5µVp-p (0.1Hz to 10Hz) makes this voltage reference ideal for sensitive applications where noise can be a critical factor.

The device operates from a wide supply voltage range of 2.7V to 5.5V, consuming a low quiescent current of 180µA (typ), which is particularly beneficial for battery-powered and energy-saving systems. Additionally, the MAX6070BAUT18+T features a load regulation of 12ppm/mA and line regulation of 3ppm/V, ensuring that the output voltage remains stable with varying input voltages and loads.

The MAX6070BAUT18+T comes in a compact, 6-pin SOT-23 package, which is suitable for space-constrained applications. Its small footprint allows for easy integration into a variety of electronic systems without significantly impacting the overall board size.

This voltage reference also includes a force-sense configuration that allows for remote voltage sensing, compensating for voltage drops due to PCB trace resistance. This feature ensures that the voltage at the load is accurately maintained, enhancing the performance of the overall system.

With its combination of high precision, low noise, and stability, the MAX6070BAUT18+T is an excellent choice for precision data converters, portable instrumentation, medical devices, and industrial controls where accurate voltage references are critical to system performance.
